Claims. (01. 242-5512) This invention relates'to holders of the typeused for supporting rolls of web-like material such as cloth, paper orcord and is more particularly concerned with a holder of the foregoingtype in which the roll of paper, cord or cloth is supported forfreerotation during use, but is restrained against axial displacementbeyond a predetermined range. Materials'such as paper towels,toilettissue, cloth, etc., that find frequent use in'the homeand inindustry are sold in roll form; the web of material being wound around ahollow central support or cop. In use, it is customary to supportthe-wound roll for rotation about'an-internal member over which thehollow cop or tube of the roll freely fits. In use, sheets or lengthsofthe material are withdrawn from the roll by'pulling thefree end andtearing or cutting off the length required, unwinding of the rollresulting in rotation thereof about the support.

The art relating to-supports for rolls of weblike material is highlydeveloped, and-many different types of roll holders are-presentlyavailable. Most of these'are-characterized by a central supportandflanges at either end which prevent the roll from sliding'axially oilof the support. since the rolls have to be replaced from time to timeafter they have become depleted'of material, the roll holder assembly'isusually comprised of detachable parts so that'the end caps or thelikemay be removed to-permit replacement of a roll over the central support.Quick detachable connections between the ends or caps of a roll holderand the cylindrical supporting portion thereof have been-the subject ofconsiderable studyand numerous-patents have been granted with respect tosuch connections. 1 Despite this activity, however, prior arrangementsusually involve a connection that is released by pressure somewhere onthe cylindrical supporting portion of the holder which is notconveniently accessible when .a roll change is required. Furthermore,prior. art roll holders in general are characterized by arather-largenumber of parts which renders their constructionsomewhatexpensive and their operationsubject to mechanical failures.

.It is therefore an objectof'this invention to provide-a roll holderconsisting of but two parts which is characterizedlby-a convenientlyoperable quick detachable connectionbetween an end cap and a cylindricalroll supporting portion, and which. is simplein: design so thatconstruction is inexpensive and operation is free of mechanicalfailures.

Other objects andvadvantages of this invention will be apparent uponconsideration of the following detailed description of severalembodiments thereofin conjunction with the annexed drawings wherein:

Figure l is aperspective view of a roll holder constructed in accordancewith the present invention showing the end cap in detached position;

Figure 2"is a longitudinal sectional view of the holder of Figure 1;

Figure 3 is a view in side elevation of the holder of Figure '1 showingthe cap in assembled or roll restraining position;

Figure 4 is a view in longitudinal section of a modified type of rollholder constructed in accordance withthe'present invention; and,

Figure 5 is asimilar view of another modified form of roll holder alsoconstructed in accordance with the present invention.

Referring now in greater detail to Figures 1, 2 and'3 of .the drawings,the roll holder there illustrate'dis comprised of a central cylindricalportion 10 adapted to-receive thereover the hollow tube or cop aboutwhich a roll of web or cord like material is wound. At one end of thecylindrical portion Ill is provided with an integral flange ll ofsufficient diameter to block the roll against movement oil" of thecylindrical portion atthatend thereof. The flange II is provided with aplurality of holes at [2 for the reception of screws or the like formounting the rollholder so-that the flange may perform the dual functionof restraining the roll against movement ofi'of'the-cylindrical portionat that end thereof, and may support the cylindrical portionincantilever fashion from a wall surface or the like.

Now'upon reference to Figure 2, it can be seen thatthe cylindricalportion [0 may be made of molded plastic or cast metal which is-solidfor a substantial portion of its length extending fromthelftend ofFigure 2. The right hand end of the cylindrical portion as shown inFigure 2, is provided with a number of slots I3 whichexten'dlongitudinally inwardly from the end of the cylindrical portionremote from the flange II, the slots communicating with a frusto conicalcavity l4 extending inwardly from the slotted end of a-cylindricalportion to a point slightly beyon'd'themid'dle thereof. The slotted endof the cylindrical portion isprovided with an annular, externalrim l5which is adapted to be received-in'an annular groove H5 in a cavity orsocket in anend cap 11. Thegroove I6 is complementary to-the'riml-l: andis of slightly lesser diameter than' the external diameter of the rim.

Ahead of the groove l6, and partially defining it, is an internal rim l8at the mouth of the socket in the cap ll.

It can now be seen that in normal roll supporting position, Figure 3,the cap ll and the flange ll restrain the roll supported on thecylindrical portion it! against axial movement oil of either endthereof. However, since slots I3 afford a certain resiliency to theslotted end of the cylindrical portion it, it is evident thatthe rim Iis continuously biased into firm engagement with the portions of thesurface of the cap l? which define the groove 16, thus insuring theholding of the cap in position. When a roll replacement is necessary, itis only required that the cap ll be pulled axially to the right, asviewed in Figure 3, to cause the rim 1% of the cap to wedge the rim l 5of the cylindrical portion to a sufliciently small cross section so thatthe cap may be removed. The resiliency of the material. immediatelyrestores therim to its normal unrestrained position as shown in Figures1 and 2; With the cap removed the roll may he slid over the rim l5 andon to the cylindrical portion ll Thereafter, the cap is moved axially tothe left, as viewed in'Figure 2, causing the rim to compress the rim 55which then expands again into the groove 86 to hold the cap in position.

The construction shown in Figure 4v is similar to that described inconnectionwith the Figures 1 to 3 inclusive except that the cylindricalpor-- tion I9 is made of sheet metal which is blanked, pierced, rolledand curled to produce a rim 2i! and then attached to a flange 2| bycleated tabs 22. The cap 23 is made of two parts, 24 and 25, joinedtogether at the margins. Once constructed the device of Figure 4consists of but two parts, the assembly including the cylindricalportion and the flange, and the cap assembly. As described in Figures 1,2 and 3, the rim 28' coacts with the cap 23 in the same way that therim[5 coacts with the cap l1.

Referring now to Figure 5, there is shown a roll holder comprised of asolid integral cylindrical portion 26 having an integralrigid rim 2'! atone end and an integral flange 28 at the other end. This assembly may bemade of porcelain, pot metal, aluminum, brass, plastic or wood. It isintended that. the flange Zl coact, with a cap 29 provided with aninternal rimifl and an internal groove 3i. In the previous embodimentsdescribed, the rim on the cylindrical portion is indicated as resilient.In the present case, the internal rim of the cap 29 is made of rubber oras a spring ring so that the rim 3!.) rather than the rim 2'! isresiliently held in a normal position and is compressible in a radialsense to permit detaching and attaching of the cap. 1 K
